INTRODUCTION
0.1 General
This document is part of the IEC 61800 series specifying requirements for adjustable speed
electric drive systems (PDS). Since the publication of the first edition of IEC 61800-2 several
documents of the IEC 61800 have been developed and maintained, which has resulted in
outdated references and conflicting requirements across the IEC 61800 series.
This document contains general requirements for PDSs intended to feed a.c. motors and with
rated converter input voltages (line-to-line voltage) up to 1 000 V a.c.
PDSs intended to feed a.c. motors with rated converter input voltages above 1 000 V a.c. are
covered by IEC 61800-4.
PDSs intended to feed d.c. motors are covered by IEC 61800-1.
0.2 Consistency of requirement
This document specifies requirements for PDSs under its scope for the identified topics not
covered by any other of the standards in the IEC 61800 series.
The following requirements are covered by other standards in the IEC 61800 series:
• EMC requirements are covered in IEC 61800-3;
• electrical safety requirements are covered in IEC 61800-5-1;
• functional safety requirements are covered in IEC 61800-5-2;
• type of load duty requirements are covered by IEC TR 61800-6;
• communication profiles aspects which are covered by IEC 61800-7 series;
• power interface voltage specification is specified in IEC TS 61800-8.
Generally this document provides a basic description of topics and refers to the relevant
standard for specific requirement. This is done in order to ensure consistency and avoid
conflicting requirement within the IEC 61800 series as well as minimize future maintenance of
the documents.
As part of the work inside SC22G MT9 this edition of IEC61800-2 defines basic definition as
used across the IEC 61800 series of standards.
For issues related to active infeed converters, IEC TS 62578 has been considered.
At the time of writing IEC SC 22G is developing a standard to provide requirement for energy
efficiency for BDM/CDM/PDS. The next edition of IEC 61800-2 will reference this standard
similar to the approach taken with the other IEC 61800 series standards.
As a result of the development of the IEC 61800 series of standards the need to reference
documents outside the series has decreased and especially the need to reference the
IEC 60146 series of standards has decreased dramatically.
0.3 Tool for agreement between customer and manufacturer
This document is intended to be used to create a comprehensive list of requirements to be
used as a specification between customer and manufacturer. The requirement in this
document is in itself not applicable for the BDM/CDM/PDS. Instead each topic should be
specified by the customer as a compliance requirement.

The document may be useful as a specification tool, when BDM/CDM/PDSs are built into a
final installation or application applied as a component. The following applications are
considered relevant: lift and hoist, machinery, conveyor, switchgears, heating and ventilation,
pump, wind, tidal and marine propulsion applications.
In every application, an identification of the environmental conditions under which the product
is stored, transported and operated is essential for the proper specification of the
BDM/CDM/PDSs. The environmental conditions considered should include electrical,
mechanical, thermal, pollution and humidity environmental condition.

ADJUSTABLE SPEED ELECTRICAL
POWER DRIVE SYSTEMS –
Part 2: General requirements –
Rating specifications for low voltage
adjustable speed a.c. power drive systems

1 Scope
This part of IEC 61800 applies to adjustable speed electric a.c. power drive systems, which
include semiconductor power conversion and the means for their control, protection,
monitoring, measurement and the a.c. motors.
It applies to adjustable speed electric power drive systems intended to feed a.c. motors from
a BDM connected to line-to-line voltages up to and including 1 kV a.c. 50 Hz or 60 Hz and/or
voltages up to and including 1,5 kV d.c. input side.
NOTE 1 Adjustable speed electric a.c. power drive systems intended to feed a.c. motors, and with rated converter
input voltages above 1 000 V a.c. are covered by IEC 61800-4.
NOTE 2 Adjustable speed electric d.c. power drive systems intended to feed d.c. motors are covered by
IEC 61800-1.
NOTE 3 For adjustable speed electric a.c. power drive systems having series-connected electronic power
converter sections, the line-to-line voltage is the sum of the series connected input voltages.
Traction applications and electric vehicles are excluded from the scope of this standard.
This part of IEC 61800 is intended to define the following aspects of an a.c. power drive
system (PDS):
• principal parts of the PDS;
• ratings and performance;
• specifications for the environment in which the PDS is intended to be installed and
operated;
• other specifications which might be applicable when specifying a complete PDS.
This standard provides minimum requirements, which may be used for the development of a
specification between customer and manufacturer.
Compliance with this standard is possible only when each topic of this standard is individually
specified by the customer developing specifications or by product standard committees
developing product standards.
For some aspects which are covered by specific PDS product standards in the IEC 61800
series, this document provides a short introduction and reference to detailed requirements in
these product standards.
This applies to the following aspects:
• EMC which is covered in IEC 61800-3;
• electrical safety which is covered in IEC 61800-5-1;
• functional safety which is covered in IEC 61800-5-2;
• type of load duty which are covered by IEC TR 61800-6;
• communication profiles which are covered by IEC 61800-7 series;
• power interface voltage specification which is covered by IEC TS 61800-8.
